To all whom, it may concern-.-

Be it known that I, J OHN BL'CKLEY, a citizen of the United States, and a resident of I Waterbury, in the county of New Haven and 5 State of Connecticut, have invented a new i and Improved N ail and Rivet Machine, of F which the following is a full, clear, and exact i description. 1

My invention relates to machines capable IQ of use'for making nails and rivets. I l

The chief objects of the invention are to provide a multiplex machine which can be"; used for simultaneously making a plurality.- of rivets, nails, and the like and inwhich a Very simple manipulation of the parts ,"so as to provide for making any smaller number of articles. vIn this way the machine can be em loved for making a single rivet at aitiine or orsimultaneousl v making a nail and a rivet or aplurality of either. j

Further objects of the invention are to provide means for manipulating dies and cutting-oif devicessoas to produce the dedies at the desired times, and for proitiding an adj'usiment of the wire-feeding devices 5 so that the proper length of wire to be fed for I each operation may be regulated.

In addition to these objects certain others F Will appearin the course of the subjoineddescription, which are largely dependent upon these and tosome extent contained in them.

Reference is to he had to the accompany- 3 5 ing draw ngs, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the fig ures. i

P The frame 20 of the machine is preferably set up in a shop at an angle to the walls thereof, so that the driving-shalt'21inay be 7 located parallel to the walls and 'to the other. shai'ting. 'Ihe driving-shait is provided with fast and loose pulleys-22, aslnpper23, and balance-wheel 24, asusual, and with a pinion 25, meshing with gear 26,'mouiited upon a vertical shaft 27; located atorjne'ar the center of the 1nachiiie. '1 his vertical shaft is preferably provided withbalLhear-i ings '28 at its lower end tofsupport its entire; weight. Near its upper end it is provided with a head 29, which has attached thereto an annular fian e 30, provided with an interior chin-surface 3] and said head-is also pro-" vided with a series of. earns 32, forlned'on slides 32 These cams are designed to en? gage with toggle-levers 33 "lhcse toggler levers are each provided with ashoulder-H for engagement with the cam-surfaces 32 and are held by means oi a cvlindricalpo'r (ion-35 in an opening 36 in aslide 37.] The a1 e also each provided with a rigid projection 38, having a pin 39 thereon prow -ting slot 4'0 in a; stationary plate 41. 7

It will be observed that when a cam-stirloo face 32 comes into contact with one of" the] shoulders 34 the toggle will becaused tarotate in its bearing 36 and will force the slide ind:iroutward' dire'ctionifroih {the-i t theinachitef In 'order to piil'lthe slide'b k' ro 5 upon'the interiorofthe flange30eonie H contactwith rollers 42f whrchi normally ject into 'the"dep'r'e'ssion inside the'flan inwardly; but the engagement of tliepin 39" in the slot 40 causes the lever 33 to swing would not have to be changed if other aragainst which the slides 69 and operate.-

On the upper end of each spindle is a head 48, and connected with said head is a spring 49. When it is desired to throw one of the sections of the machine out of operation, the corresponding head 48 is raised until the spring 49 rests upon the top of the easing 44, the pin 47 passing to the upper extremity of the slot 46. it will readily be Eachof the casings is provided with a.

ticles than nails or rivets were designed to be l rotate upon shalts til. one of. which is prel'erseen that when the spindle is raised in this I manner the roller corresponding to it will be raised out of connection with the cam-surfaces 31,- an d consequently the slide 237 will not he drawn back toward the center of the machine until the roller is again lowered into the position shown in Fig. 3.

In Figs. 21, 22, and 23 l have shown in more detail a means of adjusting the camsurl'aces 32. They are mounted on slides 32".

designed to move in ways 2%) in the head 29 5 ably located under each of the sections oi the machine described above and is supported by bearings 62. depending l'rom the frame of the machine. These shal'ts are preferably located. diagonally of the building and make angles of about forty-live degrees with the shaft 21. Zach shaft til is hollow. and through it passes a rod (53, provided with a projection 64 upon one end. This projection is designed to pass into a slot 65 in the pinion (it), and it will be readily understood that, the rod being prevented from turning independently of the shal't til by keys, (not shown.) when the projection a4 is pulled into the slot (55 the rotation of the pinion tit) will "arise at corresponding rotation of the shaft til, as shown at the left of Fig. in Fig. l

l are shown hand-pieces titi for operating the screw 30 is used for holding the screw 3t) in e adjusted positions.

It will be seen that the key by its peculiar shape will hold the slide firmly against the bottom, opposite side, and back of the ways in which it-rests.

The slides 37 move in ways 50, which may be secured in position by screws 51 or in any other desired manner. These slides are providedwith caps 52, bolted to them and provided with a passage in which can he placed the main body of a. bushing 53. This body is provided with screw-threaded portions 54, and nuts 55 are provided for locking it in any adjusted position, according to the location .1

of the nuts upon these screw-threaded portions. The bushing carries a die 56, which may be of any desired construction, but in l the present instance is provided with a surface suitable for the formation of the head of constructed in the same manner whether a ivet or a nail is to be formed, and, with the exception of the shape of the die, the parts l forming a rivet.

()n the shaft tll is a cam (37, operatinga roller (38. ct'mnccted with a slide (it). This slide operates in ways 70, mounted on the It is provided with an elongated slot 71. into which passes a pin 72. mounted in the frame. The slide also carries a diesection 73,which is adapted to cooperate with a second die-section 74 to hold the wire for The second die-section is mounted upon a second slide 75, also operating in the ways 70. Above the slide 75 is mounted a casing 76, which contains a spring' toothed wheel 81, which in turn is mounted upon a screw 82, engaging in the screwthrcaded portion of an opening 83 in the easing and bearing upon the upper end of the spring 77. It will be readily understood that upon turning the screw S2 and securingitin any dcsi red position by means of the pawl St) engaging with the teeth of the wheel 81 the spring can be adjusted to any desired position so as to provide for the properaction thereof.

This is shown at the left of Figs. 2 and 3, and details of it are shown in Figs. 4, 5, 6, and 7. The shaft 61 upon this side of the machine is supplied with a rod 63and its connections in the A eain SS is also provided, similar in many ways to, the cam 67, but having a somewhatdiiferent function. Reference is to ,be had to Figs. -1 and 5 for an illustration of this featurei This cam operates a roll 89 upon an arm 90,

extending from a pivoted block 91. This block is pivotally connected with the slide 37, which is similar to the other three slides, I by means of a screw 92 or any other equiva The block 91 has a split bear- I ing 91 in which is mounted a heading-die 93 i for the nails, and this die is secured in a i threaded bushing 94, having an integral nut 1 9-K. For a reason which will be referred to later it is not convenient to withdraw the die 93 sufficiently far from the place at which it operates to permit the nail produced to be j discharged from-the other dies which cooperate in its manufacture. Consequently the block 91 is provided to lift the die 93 away i from the iiail'after it has performed its function A slot 95 is provided in the block, and

passes through the slot 95, so as to limit the extent of motion of the block about its pivot.

This is accomplished in the 9 following manner. reference be n lia df'to' Fig. 7: ()n the shaft 61 is nioiint'eda ca n 109. provided with two opposite pi'ojectioi' s 110. Both of these projections are designed to operate rollers 111 on arms 112. Thcs1e two arms are pivoted on opposite sides of the shaft 6L, and each has linger 1113,1de-

The operation of this part of the device will be readily understood, and it will do I under the lower I: Figs. 13, 14,

be obvious that although I have shown only 1 jonesectionof the machine as constructed in manner,-yet two or more of the sections mule be, so made without de arting from the. "911ml". of my invention. T e' cams 67,

and, 103 are preferably made double to" provide for making two articles for each rev lution of the shafts 61.v

' InFigs. 11 and 12 is shown another form [of the means for transmitting motion 0 the slides 37 and for putting them out of operative position. In place of the cam 32/21 double cam-surface 32 is provided upon the head 29, and a corresponding cam-surface 33 is provided upon the toggle 33. One of the projections 32 is farther from the center of the head 29 than the other. This provides for additional security in the operation of the device, avoids the sudden blow of the crank, gives more time for-crushing, and prevents siip'ping'. The parts 31, 35, 37, 38,;39, and' 45.Will he the same as those shown in the other 'figures. Instead of the rollers 42 pins 42 are employed,and connected with t iem are knobs or handles 48*, which are provided with a curved surface 48 above the'plate 45. A spring 49 is provided for engaging the curved surface, so as to hold the pin 42 in'its' lowermost position when in the upper part of the surface and to hold it elevated when helc dpart thereof. It will be readily understoo that these changes come within the scope of my invention.

' In orderto provide forthe efficient operation of the device, feeding devices are mounted uponthe-machine, one for rivetsand one for'nails. A preferred form ofthe former will now be described, referring especially to 15, 16, and 17.

Upon each of the shafts 61 is mounted a gear 128, adapted to mesh with a gear 129 u on a shaft 130,'preferably at right angles to'theshaft 61. This shaft is journal'ed in a bearing 131 upon a main frame 132, which is mountedupon the main frame of the machineQ The bearing is preferably secured in position by means of a nut 133. Upon the opposite end of the shaft 130 is keyed a gear 134. This gear meshes gear 135, which in turn drives a gear 136.

These two gears are mounted upon a pai'rof vided with a shoulder 146, upon which is rothe turning of the rod or screw 152.

with and drives a obvious that when the shaft 61 rotates the The shaft 137 is mounted in stationary bearing 139 on the frame 132, While the shaft'138 is mounted'in'movable bearings 140 upon the samefram'e. A spring 141 bears upon the bearings 1 40, and a screw 142 is emp oyed to see re the spring in'close contact with the bearings and to provideforholding the bearings in lowermost positionwhen no force ,is exerted to move itjfromfthat positioli/ It will be-readily understood that the movement of thebearings 140 away from the bearings 139 is sufiiciently small to prevent the gears 1 35 and 136 from moving out of con tact with each other.

Upon the shaft 137 is mounted a disk 143, having a groove 144' for the wire to be-fed. On the shaft '138 is keyed a disk 145, protat'ablymo'unt'ed a second disk 147.. This second disk is provided with a pair of areshaped slots 148 and 149, through the former of which projects a stud 150. This stud is secured in the disk 145. by means of a countersunk nut 151, and it is obvious that, as the disks are mounted upon the same center and as the slots are formed on arcs of circles :shafts 137 and 138 will rotate inopposite directions.

drawn from the same center, the stud 150 can move through the slot 148 lengthwise. The upper end of the stud 150 is provided with a passage through which a screw-threaded rod 152 is adapted to pass. This rodis also swiveled in a stud 153, mounted upon-the disk 147. The rod 152 is provided with a groove 154, into which a in 155, secured in the stud 153, extends. will be observed that by this construction, the stud 154 being swiveled to the disk 147 and the rod 152 be-.

ing attached by means ofscrew-threads in i J the stud 150, the two disks 'can be adjusted with respect to each other upon their axesrlliy 1e top of the -stud 150 is split to provide for proper adjustment of the rod 152, and the parts are held in the desired position by means of a screw 156. It. ill be understood that both studs are capable of turning upon their own axes sufliciently to permit the proper operation of the rod or screw 152. Through the slot 149also projects a stud or bolt 157, which is secured to the disk 145 and serves to assist in clamping the disks.

Upon the edge of the disk 147 is locateda' groove\158, adapted to register with the groove 144. These two grooves together are sufficiently large to receive the wire operated upon by the machine and .to guide it. They are too large, however, to grip the wire under ordinary conditions, and consequently when the two sets of disks are rotated in the ordinary manner on the wire passing through the grooves formed between them the wire will simply be held in position ready to enter, the parallel shafts 137 and 138, and it will he. dies in the machine,

but will not be moved .f any size betweenxthese two.

When this conshafts 137 and 138 to cause the proper feed of the, wire for each nail. It will be seen that the same principle is employed in these tn 0 feed devices, although carried out in a difier- 'ent manner. l 1

While I have illustrated and described a particular embodiment of my invention, it will be readily understood that many changes ma be made in the construction illustrated an that the principle of the machine may be carried out in many other'forms, the inven tion not being limited to that illustrated.
